Panel Tuning Mode
The transceiver is adjusted in this mode.
■
Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with
a 4
Ω
dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
■
Transceiver tuning (To enter tuning mode)
To enter tuning mode, press the [ ] key while the trans-
ceiver is in test mode.
Use the [Orange] key to write tuning data through tuning
modes, and the [B] and [C] keys to adjust tuning require-
ments (1 to 256 appears on the LCD).
Use the [A] key to select the adjustment item through
tuning modes. Use the [ ] key to exit 3 or 5 reference level
adjustments (TK-5710/5710H) and 3, 5 or 7 reference level
adjustments (TK-5810/5810H).
